Tangs - Surgeonfish

Forum - The Pacific Blue Tang is a member of the surgeonfishes and is one of the most active swimmers of the available tangs. They will need at least a 75 gallon tank (284 liters), preferrably larger, to allow for adequate swimming space. More details on the profile page here: Blue Tang

Forum - the Yellow Tang gets to be about 7 - 8 inches (20 cm), lives for 5 to 7 years and likely longer. This fish is an herbivore and needs a primary diet of sea weed. The green and brown seaweeds will be accepted and it can be quite fun watching them tear into it. Not sure how long the yellow tangs from Hawaii will be available due to pending legislation in that state. More details on this tang here: Yellow Tang
